Summary
Shared Solana RPC nodes are cost-effective and fine for development, staging, or low-traffic apps, but they can suffer from noisy neighbors and rate limits. Dedicated nodes offer isolated resources, predictable performance, and lower latency for production workloads. This guide compares the tradeoffs and helps you decide which fits your Solana project.
Quick decision guide: shared or dedicated Solana RPC?
If you are prototyping, running a hackathon project, or serving a small user base, a shared Solana RPC endpoint is usually enough. Shared nodes are the default option from most providers and let you start without committing to infrastructure costs.
Move to a dedicated Solana RPC node when any of the following apply:
- Your application depends on consistent latency, for example trading bots, NFT minting tools, or real-time dashboards.
- You regularly hit rate limits or see 429 responses on a shared endpoint.
- You need to run heavy queries like
getProgramAccountsorgetSignaturesForAddresswithout degrading other tenants' performance. - You want predictable throughput during traffic spikes or token launches.
- You need a private endpoint for security or compliance reasons.
If you are still unsure, start with a shared endpoint, measure your actual usage, and upgrade when you see the signs above. Most providers, including OnFinality, offer both options, so you can migrate without changing your application code.
What is a Solana RPC node and why does it matter?
Solana applications do not talk directly to the blockchain. They send JSON-RPC requests to an RPC node, which acts as a gateway to the cluster. The RPC node reads account state, submits transactions, and streams real-time updates via WebSocket.
Solana's high throughput means your RPC connection can become a bottleneck. If your node is slow or rate-limited, users see failed transactions and lagging data, even though the network itself is healthy. Choosing the right RPC infrastructure is therefore a core performance decision.
Shared Solana RPC nodes: pros and cons
Shared RPC nodes are endpoints that multiple customers use. The provider runs a pool of nodes and load-balances traffic across them. This model is cheap because infrastructure costs are spread across many users.
Pros
- Low cost: Often free tiers or pay-as-you-go pricing.
- Quick setup: You get an endpoint immediately without managing servers.
- Good for development: Fine for testing, staging, and low-traffic applications.
- Automatic maintenance: The provider handles upgrades, patches, and failover.
Cons
- Noisy neighbors: Heavy usage by other tenants can slow down your requests.
- Rate limits: Providers enforce limits to protect the shared pool, which can block your app during spikes.
- Less predictable latency: Response times vary with overall load.
- Limited customization: You cannot tune node parameters or install custom plugins.
Dedicated Solana RPC nodes: pros and cons
A dedicated RPC node gives you exclusive access to a node instance. The resources—CPU, memory, bandwidth—are reserved for your project. You may also get a private endpoint that is not shared with other customers.
Pros
- Predictable performance: No noisy neighbors, so latency and throughput are more consistent.
- Higher rate limits: You can scale your request volume without hitting shared caps.
- Customization: Some providers let you configure the node, enable debug logging, or install custom programs.
- Better for production: Suitable for high-traffic dApps, trading platforms, and NFT marketplaces.
Cons
- Higher cost: You pay for dedicated resources, even when idle.
- More responsibility: You may need to monitor and manage the node, though managed dedicated nodes reduce this burden.
- Longer setup: Provisioning a dedicated node can take longer than getting a shared endpoint.
Head-to-head comparison: shared vs dedicated Solana RPC
| Criterion | Shared RPC | Dedicated RPC |
|---|---|---|
| Cost | Low, often free tier | Higher, predictable monthly fee |
| Latency | Variable, depends on load | Consistent, lower |
| Rate limits | Strict, shared pool | Higher, dedicated quota |
| Isolation | None | Full resource isolation |
| Customization | Limited | More control |
| Maintenance | Provider-managed | Provider-managed (if managed) |
| Best for | Dev, staging, MVP | Production, high-traffic apps |
How to evaluate Solana RPC providers
When comparing providers, look beyond the shared vs dedicated label. Check the following:
- Endpoint types: Does the provider offer both HTTP and WebSocket endpoints? WebSocket is essential for real-time subscriptions.
- Geographic distribution: Nodes in multiple regions reduce latency for your users.
- Archive data: Do you need historical state? Some providers offer archive nodes for deep queries.
- Load balancing: Does the provider automatically route traffic to healthy nodes?
- Support: What is the response time for critical issues?
- Pricing transparency: Are there hidden costs for overage or data transfer?
OnFinality provides both shared and dedicated Solana RPC options. You can start with a shared endpoint and upgrade to a dedicated node when your project grows. See our RPC pricing and supported networks for details.
When to use a shared Solana RPC endpoint
Shared endpoints are ideal for:
- Development and testing: You do not need production-grade performance.
- Prototypes and MVPs: Validate your idea without infrastructure overhead.
- Low-traffic applications: If your user base is small, shared is cost-effective.
- Batch jobs: Non-time-sensitive data fetching can tolerate variable latency.
When to upgrade to a dedicated Solana RPC node
Consider a dedicated node when:
- Your app is user-facing: Slow RPC directly impacts user experience.
- You run trading or sniping bots: Every millisecond matters.
- You handle NFT drops or token launches: Traffic spikes can overwhelm shared endpoints.
- You need consistent performance: For analytics or monitoring, predictable latency is key.
- You have compliance requirements: A private endpoint may be necessary.
How to migrate from shared to dedicated Solana RPC
Migrating is straightforward because the RPC interface is the same. Follow these steps:
- Provision a dedicated node from your provider. OnFinality offers a dedicated node service that you can spin up in minutes.
- Update your configuration to point to the new endpoint. This is usually a change in your
.envfile or config. - Test thoroughly on devnet first. Use the same methods and compare responses.
- Switch traffic gradually if possible. Use a load balancer to shift a percentage of requests.
- Monitor performance after the switch. Check latency, error rates, and rate limit hits.
Here is an example of updating your Solana web3.js connection:
import { Connection, clusterApiUrl } from '@solana/web3.js';
// Before: shared endpoint
const sharedEndpoint = 'https://api.mainnet-beta.solana.com';
// After: dedicated endpoint from your provider
const dedicatedEndpoint = 'https://solana-mainnet.onfinality.io';
const connection = new Connection(dedicatedEndpoint, 'confirmed');
Common pitfalls with shared Solana RPC nodes
Even with a good provider, shared nodes can cause issues. Watch for these:
- Rate limiting: If you see
429 Too Many Requests, you are hitting the shared limit. Optimize your calls or upgrade. - WebSocket disconnects: Shared WebSocket connections may be dropped during high load. Implement reconnection logic.
- Stale data: If you use
finalizedcommitment, data may lag. Useconfirmedfor faster updates. - Heavy queries:
getProgramAccountscan be expensive. Cache results or use dedicated nodes for such calls.
Monitoring your Solana RPC performance
To decide when to upgrade, monitor key metrics:
- Latency: Average and p95 response times.
- Error rate: Percentage of failed requests.
- Rate limit hits: Number of 429 responses.
- WebSocket reconnects: Frequency of disconnections.
You can use a simple script to probe your endpoint:
curl -X POST https://solana-mainnet.onfinality.io -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1,"method":"getHealth"}'
If you see consistent high latency or frequent errors, it is time to consider a dedicated node.

- Dedicated Solana RPC nodes offer isolated resources, predictable performance, and higher rate limits, making them suitable for production workloads.
- Evaluate providers based on endpoint types, geographic distribution, archive data, and support, not just the shared vs dedicated label.
- Migrating from shared to dedicated is simple because the RPC interface is the same; update your endpoint and test thoroughly.
- Monitor latency, error rates, and rate limit hits to know when to upgrade.
